Abstract
An identification device includes: an input unit that receives three-dimensional data including data of a tooth; an identification unit that identifies a type of the tooth based on the three-dimensional data including a feature of the tooth received by the input unit and an estimation model including a neural network; and an output unit that outputs an identification result obtained by the identification unit.
